Self-Diagnostic System: Notes

When vehicle is started, ABS system runs a self check on the following:

• Voltage (9-19 volts).
• Pump (operation, voltage supply and voltage feedback).
• System (external RFI, system open or short, solenoid valve and valve driver).
• Internal circuits.
• Communication circuits.

Any faults will set a code, ABS warning light will illuminate and ABS will not operate.
